] | We study the single production of sneutrinos with two leptons (or jets) via $\gamma\gamma$ collision in an R-parity ($R_{p}$) violating supersymmetric model. The subsequent decays of the sneutrino are also considered. The single production of sneutrinos may provide a significant test of supersymmetry and $R_p$-violatio... |
